According to the study, their approach worked startlingly well -- even in mice who had lymphoma in two different areas of their body.

They injected minute amounts of two immune-stimulating agents directly into solid tumors in mice and saw that it eliminated all traces of cancer in the animals, including distant, untreated metastases.

"In this way, 87 of 90 mice were cured of the cancer. Although the cancer recurred in three of the mice, the tumors again regressed after a second treatment. The researchers saw similar results in mice bearing breast, colon and melanoma tumors."

It's been tested on mice with lymphoma, breast, colon and melanoma tumors.

A clinical trail is being planned to test the method on human lymphoma patients.
